A disposable chopstick using a biodegradable plastic is provided to couple a first rod and a second rod integrally by using a coupling device portion and to prevent environment pollution. A first rod(2) and a second rod(10) are formed separately. The second rod is inserted into or is coupled to the first rod in an integration type. The first rod and the second rod are made of a biodegradable plastic. Coupling device portions are formed on the lower end portion and the upper end portion of the first rod and the second rod to be coupled with each other and to be separated from each other. An adhesion surface and a female screw are formed on the lower end and the inner surface of the first rod. A short rod(11) having a male screw(12) is integrally formed on the second rod. |
